You can try drilling out the side dowell pins that hold the diffuser in, use the search, I had my own personal battle with this and posted a lot of into on it.

Their main purpose is to help quiet the exhaust. That is also the reason for the shoebox of an exhaust manifold the n/a's have. The turbos didn't need them since the turbo itself helps muffle the engine somewhat. They also wanted the full exhaust energy to spin the turbo. 2nd gens can sound like a chainsaw or superbike. That is just the factory exhaust.
You can grind out those diffusers if you want to. They are made from unobtainium, a rather unknown supercompound from planet Krypton! Damn hard steel. Use a die grinder with a carbide bit (or several) not a dremel. Plan on a lot of time. It would be beneficial though since you can now enlarge the exhaust port. Good luck.
